SOLDERING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 362,150, dated IVIay 3, 1887.

Application filed December 29, 1886. Serial No. 222,874. (No model.)

To all whom, it may concern.-

Be it known that 1, WILLIAM M. Emmnrr, of the city of Baltimore and State of Maryland, have invented certain new and useful Improvements in Machines for Soldering the Heads of Metallic Cans to the Bodies thereof, of which the following is a full description, accompanied by drawings illustrating the same.

IO Figure l is a side view of the machine, showing the sections hinged together, the cans seated therein, and the guiding device. Fig. 2 is a top view of the same, showing the polygonal wheels for moving the sections; Fig. 3, an enlarged detail view of the sections as they are hinged or joined together, the can in its seat, and the collared or shouldered pulley below, upon which the belt acts to turn the cans Fig.

A, a sectional end view showing the standards which support the guiding device, the wheels, and portions of the sections for holding the cans. Fig. 5 is a sectional View of astandard and bearing supporting the polygonal wheels; also showing in section the cam attached to the 2 standard, and the lever operated by the cam for lifting the button to release the can.

A A, Figs. 1 and 3, represent the top and bottom pieces of asection mortised or otherwisejoined at their ends a a, aseries of bolts passing through the joined ends of the side pieces, A A. These bolts form the lateral sides of the sections and serve as hinge-bolts, upon which the joints of the top and bottom pieces of the section may have a slight turning movement. These bolts are provided with shoulders a a equidistant upon each bolt, and upon their narrow ends, which pass through the joints, a screw is cut to receive the nuts a. This screw is not out far enough down on the end of the bolt to pass below the frame-pieces, so that the nut a may be tightened to the end of the thread and leave the joints free to work. As thus constructed it will be seen that there a are formed a series of sections consisting of top 4 5 and bottom links joined together by bolts. Within each of thesesections is placed the mech anism which supports the can M. The top and bottom pieces, A A, are perforated centrally, and through the perforation in the top piece is passed the stem (0, and through the bottom one the stem cf.

Attached to the bottom of the stem (0 is the disk a which may be constructed with steps for receiving cans of different sizes, as shown in Fig. 3, and at the top of the stem a is secured the button a To a suitable part of the top piecc A is attached the spring a which exerts its tension downwardly upon the disk to; Another disk a is also placed upon the top of the stem a The stem a is also provided with collar to, which rests upon the bottom piece A, and at the lower end of the stem is placed the pulley a, provided with the shoulders a, to sustain the belt which drives these pulleys, as will be more fully explained hereinafter. The can is seated between the two disks a, and is held in place by the action of the spring a upon the upper disk.

B B are aseries of standards, of which there are three shown in the'drawings, located on each side of the machine. These standards support the guide-pieces b, which consist of two pieces of metal lying parallel with each other and leaving a space between them, or it may be constructed of one piece slotted 7 longitudinally. These guide-pieces are located, as shown, above and below the sections.

0 is a polygonal wheel, of which there are four, two at each end, which are the same distance apart as the top and bottom pieces of the sections A. These wheels are mounted upon the driving-shaft 0', and are located upon said shaft so as to conform to the top and bottom pieces of the sections. These wheels are intended to be turned by the shaft, and as they turn carry with them the sections and cans M seated therein. The wheels are notched, as shown at c", to receive the nuts to upon the hinge-bolts a as they pass around the wheel. The guide-pieces I) run nearly the full length 0 of each side of the machine and are cut ofi just before they reach the wheels 0. The bolts by the following mechanism: Viewing Fig. 5,

I is a standard which supports the upright shaft uponwhich is mounted the wheel 0,

which wheel contains thenotches 0 to receive the nuts a and also the notches 0 to receive the stem a, upon which is mounted the button a Between the ribs or arms of the wheel 0 are pivoted the bellcrank levers 43, each of which upon its lower arm carries the roller 2,

to while the other arm lies upon the rim of the wheel, and at its end is notched to correspond with the notch c in the wheel, so that when the moving sections reach the wheel this button overlaps and rests upon the notched end of the lever-arm i.

erected the cam i and as the wheel moves the roller 2' rides upon this cam, lifting the end of the lever under the button a This move ment lifts the button, the stem a, and the disk a, attached to the stem, and keeps them up until the can is removed or placed in its seat.

Then the roller leaves the earn, the spring a forces the disk and button down, carrying with it the lever z" to its normal position. The

apertures through the pieces A serve as j our nals for the stems (tand a. The upper disk,

u however, may be swiveled or made to turn upon its stem. The driving-pulley D gives motion to the machinery through the shafts d 3 and beveled wheels d c" and drivingshaft 0.

Upon a suitable part of the frame are erected the shafts e 0, upon which are mounted the gear-wheels 0 e which mesh into the wheel 0, mounted upon the shaft 0, and receive their movement from that shaft. Upon the shafts e a are also mounted the drums 0*, which are located on the shafts so as to be in line with the pulleys a attached to the spindles or stems a Around these drums a belt, 6

is placed, which runs against the pulleys a and gives a revolution in a reverse direction to the stems a and to the cans seated within the sections. The collars a on the pulleys a keep the belt from falling or sagging. Thus 5 as the sections with their cans move in one direction the cans are turned. in the other.

Before the cans are seated within the sec-.

tions a small piece of wire or drop solder is placed inside, which, when melted, finds its way around the seam of the can-head. A suitable flux is also placed therein, and as the cans are moved along in their sections and revolved they are subjected on the outside to a suitable heat, which, heating the tin, melts the 5 5 solder by conduction, which readily flows around the seam. A good way for heating the cans is by a series of gas-jets, or a series of flames from Bunsen or hydrocarbon burners, which are regulated to play their flames upon the seam from below, as shown in Fig. 4, in which H represents one or more burners. In order that the can may not be heatedover a greater surface than is necessary, the following devices are arranged to protect the longitudinal seam and lower head of the can M from too much heat: Upon the hingebolts a are placed the collars a, and upon these collars are Upon the standard I is placed the plates a, which cross the space between the two bolts and have circular openings for the can. The opening is just sufficient in size to admit the can and prevent the flame from injuring the side seam. There is also placed upon the guide-pieces an upright strip or plate, h, the upper edge of which reaches to within a short distance of the bottom of the can and protects its lower head from the heat. The space formed between the two pieces a and h exposes the head-seam only to the action of the heat, and protects the body and head of the can, as well as the lower disk and frame.

As will be seen, this machine is designed to work continuously, and may be constructed with several tiers of cans arranged within a series of sections joined by bolts moving through the entire length of the sections, and a can may be entered, soldered, and taken out of the machine upon each side, and as the section moves continuously and makes no stops each can is subjected to the heat which lasts during the time it takes to travel through one side of the machine. With a machine having a continuous movement the number of cans soldered is very much greater than with one having an intermittent movement.
